So with the ability of the home install of the tunes, I am quite surprised with so much interest, nobody has bought all 3 and did head to head comparisons. Subjectively would be nice but moreso on the dyno. I am thinking about doing this simply out of curiosity. I have ESS and happy. HOwever only would do this if it truly would be an accurate comparisons.

If you take a 2012 (mine) m3 with latest OE software, install the software again to clear adaptations and did 3-4 pulls in normal weather etc. Take peak power.

Leave car on dyno-install the next tune, 4 pulls or however many until power stopped changing.

Cool down

Next tune

And so forth. Would this be a pretty darn accurate way to compare? Than overlay the 4 graphs on each other. Would this put a lot of people to rest?

IMO, this won't happen because no singe peron is going to purchase all of the tunes on the market. Even with only the three tunes listed by the OP, you're talking about > ~$3k in tunes (assuming stage 2/HFC/no cat tunes); however, if all tunes were included then you're talking about >>>> $3k.

I don't see the point. The power difference will be minimal if any. OK, the power curve would be interesting, but there shouldn't be any big difference. Apart from that I would prefer a reliable and safe tune to one which has the highest output. This is hard to judge by a few dyno runs.

So you think max power across the rpms is the best tune? Interesting...
Personally I'd sacrifice a bit here and there for a car that ran smooth as glass and had better longevity. Unless of course you didn't realize that on a dyno you're measuring power at full throttle? Since that accounts for less than 10% of the time in which the average owner drives their car, it seems pretty irrelevant to me.
Go buy a 335, slap a single on it and hit a dynojet. You'll get your number and maybe that would keep you from trolling the M3 board. Then you may have the best tune haha!

I lean towards the measurable results, not the subjective results, so I would like to see the Dynojet SAE results. Just about everyone says their car runs better after a tune, regardless of who made the tune, so there are your subjective results. Besides, if you have the Dynojet SAE results, you will inevitably get the subjective results from the owners, but the converse is not necessarily true.

You can have consistent results on a dyno. There was a recent discussion about this, and the consensus was that you want the results to be in the same format, like Dynojet SAE, you want the conditions (weather), and you want some datalogging through the OBD port.

This could all easily be done. The problem is expense. It would be expensive to buy all the tunes and to pay for the dyno time. Unless the tuners wanted to donate their tunes and a shop wanted to donate the dyno time.

Since this is unlikely to happen, I will continue to look at the dyno results since they are the most accurate measurement of actual gains available. Eight different people with eight different tunes can all say they love their tune, but that does little for me. Even if 100 people buy one tune and say they like it and 10 people buy another and say they like that one, I would remain unconvinced that the tune 100 people bought was any better than the tune 10 people bought. More popular, yes.

Munit, stop waisting people's time with threads like this. Think before you speak. You're new here and if you searched instead of posting pointless threads you would learn a lot. I have never seen so many threads created by a member in such a short period of time. Most of them are filled will tons of misinformation and mismatched opinions.

You have any idea how many times this has been discussed in the past? Just enjoy the tune you have.

Sorry when has this actually happened? It never did end up happening when the tuners would have had to travel.

Since the home-flash devices been out, nobody has done this so where shall I see these results?

It gets talked about enough on here I believe everyone is curious

The problem as you know is finding someone who has no shop or brand affiliation and take a car, purchase all the tunes available and go to a dyno location which also has no brand affiliation and then have all the tunes run on the same day. It would be a lot of work not to mention money.

When we've posted results, we used a fully independent and well respected dyno shop that does not sell parts or has anything to gain from the results. Everyone likes Dynojets but it really doesn't matter what machine is used as people will pick out flaws and tell you why one machine is better or worse than another. The numbers game is just for bragging and we're not interested in that.

I don't convince our clients to buy our tunes or services. Our results have spoken for themselves time and time again on the forum. People come to us whether it be for the first time or the third time not because we tell them that we will give them 400hp but because we give them power coupled with driveability. We have excellent customer service and I believe that our customers will attest to that.

Lastly, with respect, it is called BPMsport. It is condescending to say benvo unless you wanna call the thread benvo vs roman vs sal. We are a legitimate business just like the other two.
